PUIiLEY-MOUNTING FOR POCKET-WINDOWS.

Specification of Letters Patent. l Patntd Oat, 17, 1916,

Application led January 10, 1916. Serial No. 71,138.

To all whom t may concern:

Be it known that I, EDMUND I-I. LUNKEN, a citizen of the United States, and a resi dent of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Pulley- Mounting for Pocket-Windows, of which the following is a full, clear, andv exact de-- scription, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to pulleys for pocket windows.

In the construction of a pocket window the difficulty is to provide weight balances for the sashes that are adaptable to a movement of the sashes throughout more than the space of half the window opening.

In a pocket window, the sashes must slide either up or down beyond the opening a distance sufcient to substantially withdraw the same from the said opening. y

Now in building a house, it is not practical to consider any other form for the window than that of a rectangular opening having a trim around it and a wall covering such as plaster or wallboard. If then a pocket were to be formed in the upper wall above the opening, it would be imperative to mount the pulleys for the window sashes in the upper end of the pocket, or else some special type of weight required or some sort of a weight box would have to be formed between the window sill and the floor. This is the fact because the windows would not be counterbalanced throughout their entire movement up into the pocket, unless there was enough room for a like movement of the weight in a downward direction.

There is no practicability in boxing up the pulley mounts in a wall pocket where it would be necessary to pull down the-wall to get at the pulleys both for installation and repairs, and for this reason various devices have been constructed to get away from the seeming impossibility of using the ordinary type of window mounting and balancing weights in a pocket window.

It is theobject of my invention to provide a means for mounting pulleys in pocket windows so that the pulleys are in the upper end of the pocket, the mounting means for them being such that it is installable and removable from the window opening.

This object and other advantages to be noted I accomplish by that certain construetion and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawing, Figure 1 is a front eleva` tion of a pocket window, broken away at the upper right hand corner to show the new pulley mounted. Fig. 2 is a central vertical section ofthe parts shown in Fig. 1. Fig. 3 is a perspective view of the preferred form of pulley device. Fig. 4 is a central longil tudinal section thereof. Fig. 5 is a central longitudinal section `of a modified pulley mount. Figs. 6 and 7 are sectional views showing modied pulley devices.

For a window frameI provide the usual parts that are to be found in a sliding sash window. That is to say, there is no modiiication in the parts of the frame except that they are made half again as long as the usual window. Thus there are the two Stiles 1, 1, having the projecting strips 2, 2, for forming the sash guides in c'onnection with the parting strip 3. On the outside strip 2 there are mounted the two channeled strips 4, 4, for an upper and a lower screen.

There are spacedv away from the stiles and forming the outside members of the frame the two weight box forming boards 5, l5. There is the cap 6, which is mounted on the side boards 5, 5, and to which the stiles are suitably secured. There is, then, the sill 7 supporting the side boards and the stiles. The upper one third of this frame, which is the wall pocket portion, is covered by a suitable cover board -8 and over this board is placed the wall finish of the room, plaster, wallboard or the like. The trim of the window is mounted around the opening left after covering the pocket, and comprises the usual captrim 9, side trims 10, 10, and subsill 11. l y

For mounting the pulley devices, which I will now describe and in which resides my invention, there are cut in the two stiles before setting them up the long slots 12, 12, two for each stile. These slots are cut at the point where it is desired to have the pulley for the weight cord, and thus their location is approximately at the top 0f the Stiles. The slots are cut in the slideway formed between the extending strips on the stiles and the Stiles are grooved or channeled,

at 13 from the slots down to a point which will be below the cap trim of the completed window, as has been described above.

The pulley mounting device comprises a long stout arm 111, which lies when mounted in one of the channels 13. At the upper end of this arm is secured the pulley retaining member having interspaced side guards 15 for the pulley 16, between which is set up a rivet 0r the like for journaling the pulley. In the preferred form, there is formed integral with the side guards an upwardly extending tongue 17.

The slots in the stiles being made longer than necessary to receive the pulley and its side guards, it is thus possible, by grasping the end of the arm 14, to tip the whole pulley device into place with the tongue 17 engaging behind the stile, and the arm 14: lying in the channel in the stile. A screw 20 inserted through the lower end of the arm into the stile will securely hold the device in place, as the weights act to hold it down very securely, against working upwardly because of the size of the slots 12.

F or inserting the weights in the box formed for them between the portions of the frame and the side trim and wall pocket cover, there is left the usual mitered opening in the stiles in which is fitted the door 21. This door, as is customary, is held in place by the parting strip on the stiles. The usual practice of feeding a cord over the pulley until it drops to the bottom of the weight box and there securing it to the weight, can be followed as easily with a pulley mount now described as in theI ordinary window. The cord is placed over the pulley with a nail or some small weight on it, the pulley is tipped into place from the window opening without reaching up into the pocket at all, and the screw 20 inserted below the cap trim. The cord or string can then be fed over the pulley until the end is within reach at the bottom of the weight box. There is no need with this device, of special weights, exposed weights or the like. There is no need for special type of stile or for any peculiarity of design of the parts of the window. All that is needed is to slot and channel the stiles, provide longer stiles than the size of window opening calls for, cover the pocket so that it will not be filled with plaster or hair, and a window bearing no difference in appearance to the ordinary window is provided, having the additional feature of being capable of the entire removing of the sash and screens from obstructing the opening by sliding them up intol the pocket.

It is readily possible that modied means of mounting pulleys in wall pockets embodying the spirit of my invention might be accomplished. For example, it would be possible to make the entire upper end of the stile removable. One way of accomplishing this modification would be to channel the board forming the cap of the window frame as at 22, and provide a plate 23 on the main stile portion of the window. The additional stile portion 24, ofa size to iit up into the wall pocket and provided with parting strips in continuation of those on the main stiles, would then be provided, adapted to lit up into the channel 22, and this additional stile portion could be mitered as at 25 to fit over a like miter on the upper end of the main stile portion. In installing this form of device, the whole additional stile having pulleys mounted in it in the usual way could be tipped into place, and it would remain there because of the combined weight of the sash and their counterbalance weights. rThe plate 23 and the miter would serve to hold the stile from tipping out of place at the bottom, the slot above serving the same purpose for the upper end.

There are also many different ways of providing for the engagement of the pulley mount first described in the slotted and channeled stile mentioned in connection with it. For example, the upper tongue on the mount could be omitted altogether and a lower tongue 26 provided as shown in the modification in Fig. 7. Also anV upper and a lower tongue together could be provided, the upper tongue being positioned on the inside of the stile and the lower tongue on the weight box side thereof, as shown in Fig. 6.

I do not wish to be limited to the tongue means for securing the pulley mount in an automatically demountable manner in the pocket portion of the stile, as this might be provided for in various ways familiar to the carpenter or mechanic. Neither do I wish to be limited to the method described for seating the lower end of the extended arm of the pulley mount.

I do not at this time appreciate any usefulness for my new pulley mount except in a pocket window, but I do not wish to be limited in my claims because of my failure at this time to state the full usefulness of the invention, as I intend it to be used wherever it may turn out in the future to be economical and convenient.

By the failure to mention other modifications, I do not wish to be limited to exa-ct structure in the claims that follow, but on the contrary I wish to have them include in their scope the full range of equivalents wherever such is possible.

I-Iaving thus described my invention, what I claim aspnew and desire to secure by Letters Patent, is:-
